3. A 12 % discount on a pair of washer and dryer that Gayle purchased, amounted to $156.00. Calculate the net price.

For this case we know that the price after the 12% of discount is 156 and we want to findd the net price so then we can use the following proportional rule:

Where x represent the net price. And if we solve for the value of x we got:

So then the net price for this case would be $ 177.273

Step-by-step explanation:

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value
